Selector Switches

In order for this thermostat to control your system, the system type must be specified by the
selector switches on the printed circuit board inside the thermostat.
Heating System Selector (HG - HE switch)
The factory position for this switch is in the "HG" position. Leave it in this position if you have
–
STD HP a gas furnace or an oil burner. If you have an electric furnace, test to see whether the Heat
and Fan come on as expected after installation. If the Fan operation is normal, leave it in the
"HG" position. If the Fan does not come on within a minute of the thermostat calling for heat,
change the switch position to "HE". The system selector has no effect in the cooling mode.
NOTE: "HG" position is for gas and most other systems. "HE" position is for certain
electric systems having a fan relay.
System Selector (STANDARD - HEAT PUMP switch)
The factory position for this switch is in the STD position. Leave it in this position if you have
ANY system that uses gas, oil, electric, or hot water heating. If you have a single-stage Heat
Pump (no auxiliary or emergency heat source), then slide the switch to the HP position. Be sure
the reversing valve wire is connected to the correct terminal for your heat pump (Y/O) or (W/B).
